e10s?

Since Firefox is working towards multiple process (like Chrome) via the e10s aka Electrolysis project, some extensions currently don't work. I haven't tested Adguard with e10s, but does/will Adguard support e10s?

Yeah, I did more testing. Adguard doesn't work when e10s is enabled. Restarting the browser will cause Nightly to revert back and not use e10s HOWEVER there's a way to force e10s all the time! Just go to about:config and set browser.tabs.remote.autostart to true and restart Nightly and it'll work all the time... but Adguard won't work at all. Keep in mind Nightly can be pretty buggy in this state so loading pages may have issues when running e10s.

No problem! Since e10s actually has a roadmap to release (Feb 2015 was the earliest I saw) I thought it might be good to at least have a heads up about it and the changes needed to all Firefox extensions to support it.
